Who is stronger a sumo or UFC fighter?

most definitely a ufg fighter if it comes to cardio, agility, and tactics/special training

<BUT...> brute strength is among both partys, a sumo could win against a ufc/ mma fighter, the chance though is unlikely, but still, it is definatly a possibility, maybe 2/10.

a sumo would win because he could just sit on the ufc fighter. or the sumo could easily drive the ufc into a corner and keep on punching him

have you ever seen that sumo wrestlers are stronger than skinny mma fighters?
